CE Certification
The product(s) described in this manual complies with all applicable European Union (CE) directives if it
has a CE marking. For computer systems to remain CE compliant, only CE-compliant parts may be used.
Maintaining CE compliance also requires proper cable and cabling techniques.
WARNINGS
Read and adhere to all warnings, cautions, and notices in this guide and
the documentation supplied with the chassis, power supply, and accessory
modules. If the instructions for the chassis and power supply are inconsistent
with these instructions or the instructions for accessory modules, contact
the supplier to find out how you can ensure that your computer meets
safety and regulatory requirements.
CAUTION
Electrostatic discharge (ESD) can damage NSA components. Do the
described procedures only at an ESD workstation. If no such station is
available, you can provide some ESD protection by wearing an antistatic
wrist strap and attaching it to a metal part of the computer chassis.
Safety Information
Before installing and using the EBC 300, note the following precautions:
Read all instructions carefully.
Do not place the unit on an unstable surface, cart, or stand.
Follow all warnings and cautions in this manual.
When replacing parts, ensure that your service technician uses parts specified by the manufacturer.
Avoid using the system near water, in direct sunlight, or near a hearing device.

Jumper Setting
EBC 300 User’s Manual 12 Appendix B
This chapter of the User’s Manual describes how to set jumpers.
Note: The procedures that follow are generic for all EBC 300 series.
2.1 Before You Begin
Ensure you have a stable, clean working environment. Dust and dirt can get into components and cause a
malfunction. Use containers to keep small components separated.
Adequate lighting and proper tools can prevent you from accidentally damaging the internal components.
Most of the procedures that follow require only a few simple tools, including the following:
♦ A Philips screwdriver
♦ A flat-tipped screwdriver
♦ A set of jewelers Screwdrivers
♦ A grounding strap
♦ An anti-static pad
Using your fingers can disconnect most of the connections. It is recommended that you do not use
needle-nosed pliers to disconnect connections as these can damage the soft metal or plastic parts of the
connectors.
Before working on internal components, make sure that the power is off. Ground yourself before touching
any internal components, by touching a metal object. Static electricity can damage many of the electronic
components. Humid environment tend to have less static electricity than dry environments. A grounding
strap is warranted whenever danger of static electricity exists.
2.2 Precautions
Computer components and electronic circuit boards can be damaged by discharges of static electricity.
Working on the computers that are still connected to a power supply can be extremely dangerous. Follow
the guidelines below to avoid damage to your computer or yourself:
♦ Always disconnect the unit from the power outlet whenever you are working inside the case.
♦ If possible, wear a grounded wrist strap when you are working inside the computer case. Alternatively,
discharge any static electricity by touching the bare metal chassis of the unit case, or the bare metal
body of any other grounded appliance.
♦ Hold electronic circuit boards (such as the EBC 300 board) by the edges only. Do not touch the
components on the board unless it is necessary to do so. Don’t flex or stress the circuit board.
♦ Leave all components inside the static-proof packaging that they shipped with until they are ready for
installation.
♦ Use correct screws and do not over tighten screws.
EBC 300 User’s Manual 13 Appendix B
2.3 Setting Jumpers
A jumper is the simplest kind of electric switch. It consists of two metal pins and a cap. When setting the
jumpers, ensure that the jumper caps are placed on the correct pins. When the jumper cap is placed on
both pins, the jumper is SHORT. If you remove the jumper cap, or place the jumper cap on just one pin,
the jumper is OPEN. Please see the following illustrations
The illustrations on the right show
a 2-pin jumper. When the jumper
cap is placed on both pins, the
jumper is SHORT. If you remove
the jumper cap, or place the
jumper cap on just one pin, the
jumper is OPEN.
Open (Off) Short (On)
These illustrations show a 3-pin
jumper. Pins 1 and 2 are SHORT.
